Abstract

LA PRESENTE INVENCION SE REFIERE A UN NUEVO DISPOSITIVO PARA ACOPLAR, POR ROSCAS DE TORNILLO, DOS DISPOSITIVOS ENTRE SI, CARACTERIZADO PORQUE EL PRIMER DISPOSITIVO TIENE UN MAYOR INDICE DE DILATACION TERMICA QUE EL OTRO, Y LOS DISPOSITIVOS SE MONTAN A UNA TEMPERATURA INFERIOR A AQUELLA A LA QUE ESTAN NORMALMENTE SUJETOS AMBOS DISPOSITIVOS. EN PARTICULAR, EL NUEVO DISPOSITIVO MANTIENE LA SEGURIDAD DEL ACOPLAMIENTO EN DONDE LOS DIFERENTES INDICES DE DILATACION TERMICA PROVOCARIAN NORMALMENTE EL AFLOJAMIENTO DE LA UNION POR ROSCA DE TORNILLO.
